    Can you imagine a world without a writing system for your language? It may be hard to picture it now, but a man named Sequoyah lived in such a world. Sequoyah was a member of a native American tribe(部落), the Cherokee. Cherokee people speak their own language, but for hundreds of years they did not have a system of writing. Without a writing system, the Cherokee had no newspapers or books before 1809.

    Sequoyah was probably born around the year 1770 and lived with his mother in a small village in the mountains of Tennessee. When he grew up, he became a blacksmith(铁匠). When he was doing business with those “English-speaking people”, he noticed that they used paper with marks to record their thoughts and ideas. Sequoyah called these pieces of paper with marks “talking leaves”. He began to wonder why people who spoke Cherokee did not have a way to write down their words.

    In 1809, Sequoyah decided to give the Cherokee their own “talking leaves”. At first he tried to make a different symbol for every word in the Cherokee language. But in that case, there would be so many symbols and too hard for people to remember, so he decided to make a picture for each syllable (音节). After much hard work, Sequoyah invented 85 symbols. In order to see whether it would work, he helped his six-year-old daughter Ayoka learn each symbol and found she could learn to read and write very quickly. Sequoyah's invention was a success!

    Before long, Sequoyah's writing system had spread far and wide. Cherokee people living in all different parts of the country learned to read and write. In 1825, Sequoyah's system was made the official written language for Cherokee people. To this day, Cherokee speakers still use Sequoyah's writing system. In some parts of the United States, you can see street signs and billboards written in both English and Cherokee. Sequoyah will always be remembered for his important contribution（贡献）to Cherokee people.

    There was a tree in my garden. One day, two birds came to the tree and built a house for their three babies. One day, I heard the sound of these birds. I ran to the garden and found two babies eating food on the ground. A few minutes later, the father bird and the mother bird came back. They brought some food for the third baby. The father bird put the food on the ground，far away from the third baby. To get the food, the baby had to fly to it.

    The third baby was hungry, but she was afraid to get out of the nest. To my surprise, the father bird and the mother bird just stood there and did nothing.

    After about ten minutes, the third baby bird didn't have any other choice. She slowly went to the border (边缘) of the nest and began to fly. Finally, she landed safely on the ground and enjoyed the food. Just like the birds, if you want to get something you want, you must depend on yourself.

    Hello, boys and girls. My name is Li Jing. I am thirteen years old. I think as students, we should work hard at school on weekdays. So I always study hard when I am at school, but on my day off(放假) I often do something else to relax myself.

    I had a very relaxing day off. In the morning, I got up at seven o'clock. Then I went to run with my father. I think we need to exercise every day. After running, I took a shower and had breakfast. At nine o'clock, I went to the zoo with my friends. We saw some pandas and lions there. Pandas are cute and lions are scary. In the shop, we bought many gifts. We had great fun there.

    In the afternoon, my parents took me to see my grandparents. They live in the beautiful countryside. They were very happy to see me. I talked with my grandfather for long and he told me many interesting things about him. My grandmother cooked lots of delicious food for us.
